Making a Video using only text, correct way to do this?
Since Blender 2.76 (or more exactly since the Gooseberry Branch) there is a new Text Effect strip that you can add in the VSE which should help you do what you want to. There are already enough tutorials out there if you need some help.

Just Add Shift+A an E&#x332;ffect Strip... T&#x332;ext. You can animate it's opacity if needed and change it's size and position.
